April 2025 monthly summary for chipsalliance/i3c-core. Focused on stabilizing core behaviors, expanding verification, and tightening build and test processes to accelerate delivery with lower risk. The month delivered a mix of bug fixes, feature improvements, and infrastructure upgrades that improved reliability, performance, and maintainability across the I3C core and its tests.

March 2025 monthly summary: Delivered substantial verification and quality improvements across chipsalliance/Cores-VeeR-EL2 and chipsalliance/i3c-core. Key features delivered include expanded verification coverage for the el2_ifu_mem_ctl block with CI integration, and PMP configuration documentation updates to reduce misconfiguration risk. In i3c-core, added visibility enhancements for reg_map in PeakRDL Cocotb, enabled default ID filtering, introduced AXI ID filtering tests, and executed multiple verification and test-plan improvements, along with dependencies and tooling updates. Major bugs fixed include undriven logic and inferred latches in i3c-core, incorrect INDIRECT_FIFO_CTRL read path in recovery_executor, and initialization of undriven inputs in CCC verification. Overall impact: improved verification coverage and CI feedback, reduced risk in PMP/IP configuration, and stronger code quality across the merged work. Technologies/skills demonstrated: Cocotb-based verification, AXI/I3C protocol understanding, test automation and CI integration, lint remediation, documentation improvements, and upstream module alignment.

Concise monthly summary for February 2025 across three repositories, focusing on delivering a standardized memory interface, improved verification coverage, CI reliability, and configurable AXI ID filtering, with notable DMA verification improvements and up-to-date upstream fixes.

Month 2025-01: Expanded verification coverage and testbench stabilization for antmicro/Cores-VeeR-EL2. Delivered extensive CSR access validation for dec_tlu_ctl (M-mode and D-mode paths), added tests for MTVEC, MHPME3-6, MDSEAC, MRAC, MEIPT, and CSR R/W, plus D-mode CSR access and EL2 testbench integration. Centralized CSR map and expected outputs for consistency across tests. Modernized the testbench with timing utilities and IO normalization, added hex-program generation by user mode, and improved regression reliability. Several bug fixes and test hygiene improvements to stabilize CI and enable faster release cycles.

October 2024: Delivered a comprehensive DCLS (Dual-Core Lockstep) documentation draft for the VeeR EL2 Core in antmicro/Cores-VeeR-EL2. The documentation covers architecture, error handling, and the validation plan, establishing a foundation for design reviews and future integration.
